Science Method of attempting to arrive at objective truths Use of evidence to make explanations and predictions of natural phenomena Hypothesis Proposed explanation for a problem or observations Scientific Method Process of creating explanations about the world and testing those explanations with experiments and data Evidence-Based Practice Three-pronged approach to working with clients What are the 3x prongs of Evidence-based Practice Weight of the evidence from scientific research Field observations Individual client needs and preferences Prediction Expected outcome generated from a hypothesis. Steps of the Scientific Method (5x) Idea - identify the problem Generate hypothesis Design an experiment Acquire and analyze data Accept & keep testing OR Reject and generate a new hypothesis True or False: Scientists identify what is most likely to be true by demonstrating what is not true. True Theory Hypothesis or set of hypotheses for which a lot of high-quality evidence has been gathered Anecdote Account of a person's experience Uncontrolled Variable Variable in an experiment that scientists make no effort to change or account for Primary Research Original research Scientists perform experiments & collect data Secondary Research Scientists analyze data that has already been collected or published Observational Research Observes ongoing behaviors in order to determine if correlations exist Correlation ≠ causation Correlation Relationship between 2x or more variables Not cause & effect Independent Variable Variable you have control over; can choose and manipulate Cause Dependent Variable Possible outcome of the experiment Effect Confounding variable Any variable that has an effect on your dependent variable outside of your independent variable Randomized Control Trials (RCTs) Participants are randomly assigned different groups One group is the group being tested The other is the control group (placebo or no treatment) External Validity Generalizing the results of a study Systematic Reviews Scientists gather all research on a topic and evaluate it based on predefined criteria and rules Meta-Analysis Statistical analysis of RCTs; a study of studies Empirical Based on observation or experience Test-Retest Reliability Getting similar results when something is measured under the same conditions Reliability consistency of measurement
